Watch online videos in cinema style with Turn Off the Lights [Internet Explorer, Chrome, Firefox, Opera, Safari]

It’s not everyday you find a browser extension available for all the major browsers so this must be a special day. Turn Off the Lights is available for Internet Explorer, Chrome, Firefox, Opera, and Safari and it will improve your online video watching experience. However, if you are still afraid of the dark, this is not an extension for you.


Turn Off the Lights (TOtL) makes everything around the video you are watching go dark. That way you can focus on the video and nothing else. TOtL is especially designed for video sharing websites like YouTube or Vimeo and social networks like Facebook, Myspace, and similar. And yes, Nelly Furtado has a track with the same name.


Once TOtL is installed you will see the lamp icon on your browser toolbar. To activate it, just click on it:

Hitting that icon makes everything except for your video go dark.

TOtL comes packing several options and features for you to choose from. Here are the most relevant ones:

Let turn you lights automatic off when you play a YouTube or even watch a HTML5 video. And if you click the pause button, it will return back to the original appearance of the page.
Click back on the play button, it will fade back into the darkness.

Fade effect:
The effect you see from light to dark is called the fade effect. This is one of the most important part of an entertainment in this extension. By default, the opacity by apparently is set to 80%. But you can always change it in the options page.

Do you not like black? Then you can choose between thousands of different colors in the options page. Or just show your own background image.

Flash Detection:
If you enable this option, it will search for all the Flash player, Flash games, etc. And give them all focus to the foreground.
This option is especially interesting for internet games you want to get focus on it.

I tried TOtL on YouTube…

…and always with the same result: awesomeness!


I’ve to say that I didn’t find TOtL by accident. Some days ago I thought to myself: “By now there has got to be an extension that surrounds videos with darkness” and bam! — here it is, just what I wanted and more… plenty more.

    @BarrysCool: That´s actually very movie theater style. In Portugal at the movies the lights work just like that and when the movie has an intermission (which I personally dislike) the lights go back on. Happy you like it.

    @Ashraf: The joys of multitasking are endless indeed but you put it correctly “to each his own”.

    @graham: It´s working for me but here it is:

    This is an excellent find Leandro. The only issue I’d have is if I were not watching a video in full-screen mode, that would mean I’m multitasking and wouldn’t wanna turn everything black. However, to each their own.

    Thanks for the heads-up, it’s a great little add-on to Chrome.
    Interesting to note that in Auto-mode the dark background doesn’t click in until the advertisement has finished. Likewise if the advertisement is contained half way through the video the lights will again come-on until the ad is finished, then will go out again until the end of the video. This bit is annoying to say the least, otherwise a great little add-on.
